Bell System Practices
The Bell System Practices were a set of documents produced by the American Telephone and Telegraph Company to instruct employees on the proper use and maintenance of all kinds of telephone equipment.
As these materials span decades of the history of (what was at the time) the world's largest corporation, the quality varies widely. Some documents are carefully phototypeset originals, some are enlargements from microfilm, and still others are third-generation photocopies of typewritten originals.
